Info for wiring LED harness switch into 2013 cab/dash?

Hello,
I bought and installed an Extreme LED 22" 200w lightbar on my ARB bumper, but I'm not sure how to get the on/off switch "into" the cab... So it looks nice but not working yet.
Any suggestions? or direct to any earlier post / reference, etc? Any help appreciated.

 

In the engine bay driver side, there is a grommet to go into the cab, will come through above your break pedal. Will probably want to remove the wires from the switch when you pass it through.

 

Thanks. I'll give it a try!

 

OK, done.
I used a long 1/4"SS rod cut @ 45 deg- with the wire connector taped - to pierce the boot from the inside.
Light works and so does the switch cut into the lower dash.

thx.
